In other words, the speed of a Bullet (Rifle) is 1 times 0.00000305 times the speed of light.

(5.56 x 45 mm, a.k.a. 5.56 NATO)A 5.56 x 45 mm cartridge is fired at a velocity of 0.00000305 times the speed of light. As the NATO rifle cartridge, it is used by the military forces of more than thirty-one countries, including use in the M16 series, M4 Carbine, HK-416, and M249 Squad automatic weapons used by the United States armed forces.

In other words, 0.00000305 times the speed of light is 8.47 times the speed of a Peregrine Falcon, and the speed of a Peregrine Falcon is 0.118 times that amount.

(a.k.a. Peregrine, a.k.a. Duck Hawk, Falco peregrinus)The Peregrine Falcon can reach speeds of up to 0.00000036 times the speed of light when diving. Falcons are sometimes sent to scare smaller birds away from airports to improve air traffic safety and were used in World War II to intercept carrier pigeons used by enemy forces.

In other words, the speed of The CRH (train) is 0.11 times 0.00000305 times the speed of light.

(a.k.a. Hexie Hao, 和谐号, a.k.a. 和諧號, a.k.a. Héxié Hào, a.k.a. "Harmony")The CRH-3 train which runs on China's Beijing-Tianjin Intercity Railway are capable of speeds up to 0.00000032 times the speed of light. Theses train can make the 120 km (74 mi) journey from Beijing to Tianjin in about 30 minutes.
